• Eight cases of delayed nonexpulsive suprachoroidal hemorrhage occurred after filtering operations in aphakic eyes. Sustained hypotonia resulting in serous choroidal detachments, scleral infolding, or both was observed prior to the hemorrhage in seven of the eight eyes. The prognosis was related to the extent of the hemorrhage and possibly to whether or not surgical drainage was performed. Only one of the five patients with massive hemorrhages recovered visual acuity better than hand motions; that patient had undergone prompt surgical drainage of the suprachoroidal blood.
